Specification of Letters Patent.

Patented Mar. 21, 1916.

Application filed. June 17, 1915. Serial No. 34,569.

To all whom it may concern: 1

Be it known that I, JOHN GArr, a citizen of the United States, residing at Scranton, in the county of Lackawanna and State of Pennsylvania, have invented a certain new and useful Improvement in Track-Sanding Devices, of which improvement the following is a specification.

This invention relates to track sanding devices for locomotives, and is in the nature of an improvement upon the apparatus of my prior Patent No. 1,102,577, issued July 7, 1914, the object being to provide a more simple and compact structure of the type having both a fluid pressure feed and a hand operated gravity feed, and which may be readily applied to the standard designs of locomotive sand boxes.

In the accompanying drawings: Figure 1 is a side elevation of a locomotive sand box and a portion ofthe boiler showing one form of my improvement applied thereto; Fig. 2, a view partially in elevation and partially in central longitudinal section of the sanding device shown in Fig. 1; Fig. 3, a transverse section taken on the line w:v of Fig. 2; Fig. i, a plan of the rotary valve; Fig. 5, a side elevation similar to Fig. 1, and showing a modified form of my improvement; Fig. 6, a view partially in section and partially in elevation, of the device shown in Fig. 5; Fig. 7, an inverted horizontal section taken on the line g g of Fig. 6; Fig. .8, a longitudinal'section taken on the line ez of Fig. 9, and showing another modification; Fig. 9, aninverted plan of the device shown in ig. 8, with a portion of the bottom plate broken away; and Fig.

. 10, a perspective view of one of the insert blocks used in the construction shown in Figs. 8 and 9.

According to the construction shown in Figs. 1 and 2, my improved sanding device comprises a casing, 1, preferably in the form of a single casting, having an opening at its upper end for connection with the locomotive sand box, 2. Within the casing are.

formed the passages, 1, leading to the sand receiving chamber, 3, and the gravlty discharge'passage, 7, leading from port, 2*, in

the valve seat to the sand delivery pipe, .8. The sand receiving chamber communicates with the gravity discharge passage by means of the upwardly curved delivery passage, 7 An air chamber, 4, is also formed in the casting, to which the compressed air supply pipe, 5, is connected. This chamber serves as a separating, chamber in which moisture and other foreign particles-contained in the air supply may be deposited and removed at convenient times by taking out the cleaning plug at the bottom of the chamber. The air then passes through an opening from the top of said chamber into the space, 6, around the spool-shaped air nozzle, 10, adapted to be screwed into its position from the exterior of the casing and having a perforation, 11, in line with the sand delivery passage, 7*, whereby the blast of air blows the sand in a continuous stream from the chamber, 3, through passage, 7, into the sand discharge passage, 7 and delivery pipe, 8.

In the double form of sanding device, as shown in the drawings, the parts are duplicated on opposite sides of the center, one p pe, 8, leading to the front of the drivers and the other pipe leading to the rear of same, and the manually actuated valve, 9, positioned on the valve seat controls the gravity discharge ports, 2 to either the front or rear delivery pipes. WVhen the valve is in its middle position, both ports, 2, are closed, and the sanding device may then be operated by the air blast through either or both of the pipes, 5, as desired. By turning the valve, 9, in one direction from its middle position, one of the ports, 2 is opened to discharge sand by gravity directly to the corresponding delivery pipe, and when turned in the opposite direction, the other gravity port is opened to discharge sand through the other pipe. Any suitable form of mechanical connections may be employed for manually operating said valve, such as the valve stem, 14, extending vertically through the casing between the discharge pipes, and provided with crank arm, 12, and rod, 13. A spring, 15, may be used for holding the valve upon its seat. Aremovable hand hole plug, 18, affords access to the valve and its seat.

As the upward curved wall of passage, 7 is subject to the cutting action of the sand which may rapidly wear away the same, I propose to insert at this point a removable wall section, 16, adapted to be slid into a cored recess in the casing and securely held therein by a screw plug, 17 When this section becomes worn it may be readily replaced with a new section by simply removing the screw plug, as will be readily understood.

According to the modification shown in Figs. 5 and 6, the portion containing the sand receiving chamber and the air chamber is formed as a separate section, 3, suitably bolted to the manifold section, 1 and to the section, 3, is attached the section, 7", containing the gravity discharge passage, 7, and the delivery passage, 7 communicating therewith, the discharge pipe, 8, being connected to the section, 7*. In order that the section, 7 may be renewed separately Without disturbing the other parts, the upper end is tapered to slidingly engage an opening in the flange, 3 of section, 3", which is also provided with a projection, 3 having a recess adapted to receive the flange of the section, 7", the parts then being secured by the single bolt, 20. IVith this construction, it is a simple matter to renew the section, 7", by removing the bolt, 20, and detaching the'pipe, 8. In this modification the rotary valve, 9, controlling the gravity discharge ports, 2*, is operated by the bevel gears, 21 and 22, and shaft, 23, extending through the side of the casing, 1 and attached to the crank arm, 12, and operating rod, 13. The operation of this form of the improvement is substantially the same as before described. While the double form of sanding device is shown in the drawing, it will be obvious that a single sander may be employed wherever desired, and that in v such case the parts on one side are omitted.

The modification shown in Figs. 8 and 9 is adapted for use in connection w1th a locomotive sand box having separate openings for delivering sand to the air jet and to the gravity discharge. In this construction the part, 2*, indicates the flange of the sand box having openings, 1*, communicating with the sand receiving chamber, 3, of the air jet device, and 1, leading to the gravity valve, 9. The casing is substantially the same as that before described, except that the gravity discharge passages, 7, and the delivery passages, 7 are contained in separate blocks, 7, inserted into large rectan- V gular recesses in the bottom of the casing and secured therein by means of the plate, 19, bolted to the bottom of the casing. A gasket, 24, may be placed between the plate and the insert blocks for maintaining a tight joint. When the blocks become worn due to the cutting action of the sand blast, they may be readily renewed by simply removing the plate, 19, and substituting new blocks in the place of the old. As shown in Fig. 8, the air jet nozzle, 10, has the port, 11, extending longitudinally through the same and closed at the outer end by a plug, 10

so that in case the port should become clogged, it may be readily cleaned out by simply removing the plug,10, and running a wire through the hole. This avoids the necessity of removing the jet nozzle. A cylindrical band of wire mesh, 10, may be placed on the spool, 10, over the port leading to the perforation, 11, for preventing the entrance of dirt into the nozzle. It willbe obvious that either form of jet nozzle may be used with any one of the modified forms of sanding devices. The valve, 9, is operated to control the gravity discharge passages in the same manneras heretofore described. The bottom plate, 19, is provided easy vfitting and the accumulation of line sand dust which may readily fall out when the bottom plate is removed for cleaning.

Having now described my invention, what I claim as new and desire to secure by Letters Patent is: V

1. In a track sanding, device, the combination of a casing containing a sand receiving chamber, a passage for supplying sand thereto, a valve seat with said chamber, a gravity discharge passage having a separate sand supply port leading from said valve seat, a delivery passage from the said chamber to the gravity discharge passage, an air jet nozzle discharging into said delivery passage, and a'rotary valve on said valve seat and controlling said gravity supply port.
